■■■ Universal Unpacker ■■■ Version 1.33b (C) 1995-97 Jürgen Peters My address: Sundernstr. 30 D-33829 Borgholzhausen Germany Fax/BBS : +49-5425-4405 FidoNet : 2:2432/344 VirNet : 9:493/4244 ZyXELNet : 16:4902/144 GerNet : 21:100/1744 OS2Net : 81:491/3244 PascalNet : 115:4905/1270 TreiberNet : 405:3260/973 eMail : Gray.Beast@t-online.de UU is a simple tool to identify and unpack compressed files of different formats, a clone of the well known 'General Unpack Shell' (GUS), but much more powerful. A german version of this program is also available. Look for the file UUnnn.* (without the 'e' for 'e'nglish version; nnn = version number). Eine deutsche Version dieses Programms ist auch verfuegbar. Schauen Sie nach UUnnn.* (ohne das 'e' der englischen Version; nnn = Versionsnummer). -------------------------------------------------------------------------------- ATTENTION!!! This program is still rather experimental. There may be some bugs in it. Use it at your own risk! For operation of the program (except for archive identification with /I) the corresponding unpackers need to be found in DOS's PATH statement. I hereby release this version as FREEWARE This status may be changed in later versions! The copyright stays at the author and the program (all files) is not to be disassembled or altered in any other way. It is allowed to share this software with others if no fee is taken (except of copying fees by shareware vendors etc.). Members of FTN-compatible nets are encouraged to send me a netmail if they use UU on a regular basis (answering only possible over Fido- or ZyXELNet). Suggestions and constructive critique are always welcome. ------------------------------------------------------------------------------ Operating instructions ======================= Syntax: UU archive name [filespec(s)] [targetpath\] [switches] (Exactly in this order.) All parameters in brackets are optional. Meaning of the parameters: Archive name: The archive or sfx file to be unpacked (wildcards allowed). Supported Formats: ARC, ARC+, PAK, ZIP, LZH, ARJ, UC2, ZOO, DWC, PUT, HYP, LBR, HA, HAP, HPK, SQZ, SQWEZ, LIM, RAR, MD, BSN, BS2, AIN, SAR, ACB, MAR, CPZ, JRC, JAR, ARX, Quantum, ReSOF, QuArk, YAC, X1, Codec, NuLIB, PAKLeo, AMGC, ChArc, PSA, ZAR, LHARK, CrossePAC, Freeze, KBoom, DPA, TTComp, CAR, WIC (fake!!), RKive, JAR, ESP, ZPack, SKY, ARI, UFA, FOXSQZ, AR7, TSComp, PPMZ, MP3, ZET, ARQ, ACE, Squash, Terse, Stuffit, UHarc, ABComp, CMP, LZO, szip, Splint, TAR, InstallShield Z, BOA, ARG, Gather, QFC, WWP-Data, XPack-Data, XPack-Diskimage, XPack-SData, Crush and Sfx files. Filespec(s): The file(s) to be decompressed (wildcards allowed). Targetpath: Directory to unpack the archive into (default: current dir, the backslash at the end is mandatory). Switches: /D Delete archive after successful unpacking /I Identify only, don't unpack archive /M unpack Mailarchives (see documentation) /N do Not use embedded paths while unpacking /P Print file(s) on standard output device (if possible) /Q Quiet mode, suppresses shell output (where possible) /R Replace existing files (overwrite mode) /S Scan unpacked files for viruses /T Test archive integrity /U Update mode (decomp. only newer and nonexistent files) /V View archive contents /Bdir move Bad archive to specified dir /GPW supply password PW for Garbled file /X XMS/EMS/disk swapping allowed /A target directory = Archive name Important: not all parameters work with all unpackers, if these do not support the corresponding feature. The particular switches ----------------------- /D -- The archive is erased after decompression (not, if an error occured during unpacking). /I -- The archive is identified only, not unpacked. The output of UU.EXE is as follows: C:\>UU.EXE RCVT100.EXE /I The archive type of G:\UP\PACKTOOL\RCVT100.EXE is: RAR In addition UU.EXE returns a corresponding errorlevel: 1. ARC 2. ZIP 3. ZOO 4.

Gather 112. Pack Magic 113. BTS 114.ELI 5750 115. QFC If the file format is unknown/no archive, the errorlevel 0 is returned. If the file is not found, the errorlevel is 255. Not all of these formats can be unpacked by UU! Especially EXE-packed files cannot be decompressed (other tools are available for this). Only the formats mentioned after "Archive name:" above can be unpacked. /N -- The archive is unpacked into the actual or the specified targetpath, but embedded paths are not created. /M __ This switch stands for "unpack Mail archives". Here the syntax is a little bit different than in the normal case. Instead of archive and file name(s) you only have to specify the directory, where the (mail) archives are located, eg.: UU D:\MCMAIL\INBOUND /M Then UU decompresses all archives it finds in that directory, whose extension begin with 'SU', 'MO', 'TU', 'WE', 'TH', 'FR' or 'SA' and end with a number from '0'...'Z', into that directory und automatically deletes the original archives (like with the parameters /D and /N). If another directory name is given after the inbound directory, the decompression takes place into this second directory. For example: UU D:\MCMAIL\INBOUND D:\PACKETS\ /M In this case the mail archives are unpacked to D:\PACKETS. The backslash is not mandatory in this case, but the target directory must always be the _second_ and /M the _last_ parameter. If an archive cannot be unpacked successfully, it is not erased, but moved into a directory called BADARC.$UU inside the mail directory (in the example above: D:\MCMAIL\INBOUND\BADARC.$UU). This allows it to examine problematic mail archives later on (and keeping the original names of the archives). /P -- Files are decompressed directly to the printer (PRN). Attention: if the unpacker does not support this, files may be unpacked to disk. /Q -- Quiet mode. If possible, all output of the unpacker is suppressed. /R -- Replace mode. Files already on disk are being overwritten by ones with the same names inside the archive when unpacking. /S -- Scan unpacked files for viruses. At first UU.EXE searches within DOS-PATH for a batchfile named SCANVIR.BAT (if 4DOS is detected, first for SCANVIR.BTM). In this file there may be any number of virus scanner calls with their parameters (see included sample batch). If no such batchfile is found, UU looks for F-PROT.EXE. If even this file does not exist, SCAN.EXE is being searched. At last, if no virus scanner is found, a short errormessage is put out. /T -- Invoking of the (CRC)-test option of the unpacker. Files are not unpacked. /U -- Update mode. Files already on disk will be overwritten with ones with the same names inside the archive, only if these are newer (if being supported by the unpacker). /V -- View archive contents; files are not being unpacked. /Bdir ----- If decompression fails (archive bad, not enough memory, virus found with /S etc.), the archive is moved into the specified directory 'dir'. If that directory does not exist, it is created! /G -- With this parameter a required password for garbled archives may be supplied to the unpacker, eg. UU GARBLED.ARJ /GSecret /X -- This parameter should only be applied in case of RAM shortage (eg. when calling from a shell). UU.EXE swaps itself out of memory (only 1.4 KB remaining) to XMS, EMS or disk (in this order). In case of disk swapping a hidden temporary file is created in the directory which is defined by the environment variable 'TMP' or 'TEMP' (or in the current directory, if these do not exist). Since swapping takes some time, unpacking is a little bit slower with this switch, which is therefore inactivated by default. /A -- Die Archive werden in neue Verzeichnisse mit den Namen der Archive entpackt. Archives are unpacked into new directories with the names of the archives. Example: UU TEST.RAR /A creates a directory TEST\ in the current directory and decompresses the archive TEST.RAR into it. UU TEST.RAR C:\TOOLS\ /A unpacks into C:\TOOLS\TEST\. ------------------------------------------------------------------------------ The file UU.CFG =============== In this configuration file for UU.EXE it is possible to define up to three different unpackers for each archive format. The file UU.CFG must be located in the same directory as UU.EXE. The format of the file is very simple: Name1U1=ENTPACK1.EXE Name1U2=ENTPACK2.EXE Name1U3=ENTPACK32.EXE Name2U1=ENTPACK4.EXE Name2U2=ENTPACK5.EXE Name2U3=ENTPACK6.EXE At the beginning of a line the keyword is to be placed (not case sensitive). Then a '='-char follows and after that the name of the unpack program. This unpacker must be located in a directory, which is defined by the PATH- environment variable, or in the current directory. Alternatively the complete pathname, eg. C:\TOOLS\ARJ.EXE, can be supplied. In this case the file is not searched in PATH. It is always being searched for the *first* program file. Only, if this is not found, UU.EXE looks for the second one etc. If the file UU.CFG does not exist, the program defaults of UU.EXE are being used for the unpacker names. These are identical to those in the originally delivered UU.CFG. Tip: If you are using the default settings in UU.CFG, it is recommended to erase that file. This speeds up the operation of UU.EXE significantly, because there is no need anymore to read UU.CFG line by line. UU.EXE uses the internal program defaults instead. Important hint: it is recommended to edit UU.CFG only if absolutely necessary, because UU.EXE in case of a different name of the unpacker will still use the original parameters for this new filename. Example: As the second unpacker for the LZH-format originally X1.EXE stands in UU.CFG. That means: even if another unpacker is entered behind 'LzhU2=', UU.EXE will still use the parameters for X1.EXE. In the moment UU.CFG is therefore only useful, if the other decompression program has another name, but uses the same commands. Fortunately this is true in most of the cases with standard commands. In the above example both LHA.EXE and X1.EXE use the 'x'-command to unpack an LZH- archive. With more special parameters (printing, extracting with password, overwrite mode etc.) this is not guaranteed any more. Therefore in a later version of the 'Universal Unpacker' it is planned to make all commands and parameters of each packer userconfigurable. ------------------------------------------------------------------------------ Version history --------------- 1.10 01-06-97 - First englisch version 1.11 01-22-97 - As the default unpacker for LZH files now LHARK is used. For this version 0.4a or higher in mode LHARK-B (!) is needed (change between mode A and B with command LHARK o). The advantage is, that LHARK can decompress all LZH archives (even -lh7-) and ist faster. If LHARK.EXE is not found, LHA.EXE is used like before. 1.12 01-27-97 - Enhanced error handling: if the unpacker returns an errorlevel<>0, the current action is cancelled and an error message is displayed. The command /D does not delete the archive in this case. - The switch /Bdir makes it possible to move broken archives to a specified directory. 02-01-97 - Format DRY (dehydrated) is being recognized (but not unpacked). 1.13 02-02-97 - Switch /M for unpacking mail archives implemented (like the corresponding GUS parameter). 02-03-97 - Fake-Packer OWS is identified, but (of course) not decompressed. 1.14 02-23-97 - Freeware-Packer SKY is being supported. 02-24-97 - Better RKive detection. 03-04-97 - Bug Fix: when using wildcards with archive names the switches (/T, /V etc.) were stripped. 1.15 03-08-97 - ZAR was sometimes identified as TTComp - Format ARI is recognized - but only due to the file extension. - Format UFA wird identifiziert. 03-09-97 - Microsoft's CAB (Windows 95) is being recognized (but not unpacked). 03-12-97 - Identifying of FOXSQZ. 03-16-97 - Identifying of AR7. 03-18-97 - Recognition of the Stirling Compressor (TSComp). 03-22-97 - Recognition of PPMZ. 1.16 03-30-97 - Added MS Compress (only identification). 04-02-97 - Identification and decompression of MP3 and ZET. 1.17 04-07-97 - Identifies and unpacks XPack data and diskimage files. 04-17-97 - Recognizes and decompresses ARQ archives. 1.18 04-21-97 - Better handling of X1 files. X1 0.94o or higher recommended. 04-25-97 - Improved decompressing of SKY archives. SKY 1.03 or higher recommended. 04-27-97 - Support of ACE archives (also sfxes). 05-01-97 - Implemented /T-switch for ESP (needs ESP v1.9b3). 05-10-97 - Squash by D. Murk is being recognized. 1.19 05-14-97 - Improved ACE-Sfx-recognition (identifies ACE 0.9c2 too). - Idenfication of packer Terse by Michael Nagy. 05-17-97 - Recognizes and unpacks XPack single file data 05-19-97 - Bug in commandline parsing fixed: when using wildcards in the archive name, the filespecifications and switches could become crippled. Thanks to Christian Klak. 05-20-97 - Bugfix: ACE files could not be extracted into a target directory. 1.20 05-21-97 - BS Archiver 1.6, an older version of BSN/PTS-DOS, is being identified (as BSN). For decompression BSA.EXE is being used. If not found, BS16.EXE. 05-24-97 - ACE 0.9c5 and 0.9d1 Sfx jr. are being recognized. - Stuffit (Mac) is being identified. - Improved PKZip Windows- and OS/2 sfx and WinRAR install sfx recognition. - No archive comment display with ESP with UU /T (ESP v1.9b3 or higher necessary). 05-25-97 - Because of problems of some older unpackers with multitaskers (eg. PKUnpak and OS/2) UU opens archives in sharing mode (permit all). 05-28-97 - Parameters /V and /T now also functional with XPack data files (XPack 1.67h resp. 1.67i needed). 1.21 05-31-97 - The creation of non existing target directories is now done by UU.EXE because of the different behaviour of the unpackers. 06-01-97 - Recognition of PUCrunch (identify only). 06-04-97 - ACE 0.9d3 sfx is being recognized. 06-05-97 - BZip is being recognized (identify only). 1.22 06-08-97 - ACE 0.9d4 sfx is being recognized. 06-10-97 - The following multiple volume archives are not more only recognized by the file extension, but by the volume flag in the archive header: ARJ, ARJ sfx, RAR, RAR sfx, ACE The switch /I shows, if such an archive is a volume (this is not the case with the _last_ ARJ volume, because ARJ defines a volume as an archive, which is _followed_ by another volume). 1.23 06-18-97 - Changed behaviour of /U with some packers (RAR, ARJ, JAR): until now only existent files were freshened (-n), now existent and nonexistent files are updated (-u). - /U now also functional with UNESP. - Archive test option /T works with RKive. - Reading of UU.CFG only one at start even when wildcards in archive names were used. Results in better execution speed. - ACE 0.9e3 sfx is being recognized. 06-20-97 - Totally reworked ZIP unpack routine. If Info-UNZIP was used instead of PKUNZIP UU.EXE nevertheless used the PKUNZIP commands. - Recognition of PKZip/2 2.50 sfx. 1.24 06-23-97 - With parameter /A archives are unpacked in new directories with the names of the archives. Thanks to Thomas Erbe for the idea. - Bugfix: when using wildcards in archive names sfxes were not recognized correctly. - Some internal optimizations. 06-24-97 - With /A now also a target directory may be supplied. For example UU TEST.RAR C:\TOOLS\ /A unpacks into C:\TOOLS\TEST\. 06-27-97 - Bugfix: With RAR archives the target directory with /A was (1.24c) created twice, eg. C:\TEST\TEST\. Thanks to Christian Klak for his hint. 07-19-97 - When unpacking with ARJ the environment variable ARJ_SW (1.24d) is not ignored anymore. - Recognizing UHarc 1.66 (identify only). 07-20-97 - UHarc is now unpacked etc., too. 07-23-97 - At the following archive formats it is detected, whether (1.24g) they are AV-secured or locked (through AV-Flag in header): ARJ, ARJ-Sfx, RAR, RAR-Sfx, ACE (with /I switch). 08-03-97 - Bugfix: in some cases the filemode was not reset correctly (1.24h) in sfx detection. 08-04-97 - Support for single file packer ABComp 2.04b. 1.25 08-06-97 - Major code rewrite and some bugfixes. 1.26 08-16-97 - Some bugfixes with JAR, JRC, ZET, AMGC (many thanks to George Shadoff for testing). 08-17-97 - For AMG files now Sky is used as unpacker, because AMGC.EXE itself shows a bug when creating directories. 08-18-97 - Support for format CMP (André Olejko). 08-20-97 - Smaller bugfixes. 1.27 08-24-97 - BZip2 is being recognized (identify only). 08-25-97 - BS Archiver 1.9, an older version of BSN/PTS-DOS, is being identified (as BSN). For decompression BSA.EXE is being used. If not found, BS19.EXE. - Identifies and unpacks LZO (M.-F.-X.-J. Oberhumer). - Better distinction ARC/PAK (thanks to George Shadoff). - With /I the archive type is also given numerically. 1.28 08-28-97 - Bugfix at ARJ-AV-recognition. - Crude szip detection (Michael Schindler) only by one byte and extension .SZ. - With Info-UNZIP now the parameters -s (convert spaces in filenames to underscores) and -C (match caseinsensitively) are used to improve DOS compatibility. - UNZIP.EXE (Info-ZIP) is now default instead of PKUNZIP.EXE. - Again a major code rewrite. 08-31-97 - WinZip sfxes are identified (as ZIPs). 1.28a 09-09-97 - Format Splint is identified. 1.28b 09-12-97 - Default for ZIP now UNZIP.EXE, then UNZIP32.EXE and PKUNZIP.EXE. 1.28c 09-14-97 - Sfxes are now also recognized, if they start with 'ZM' instead of 'MZ' (thanks to Pierre Foucart). 1.29 09-18-97 - Format TAR is beeing identified (only from extension .TAR). For unpacking the program UNTGZ is used (like TGZ format, see UU.CFG). - InstallShield format is recognized (identify only). 1.29a 09-19-97 - Sometimes the parameters between PKUNZIP.EXE and UNZIP.EXE (Info-Unzip) seemed to be exchanged. Although I could not reproduce that behaviour here, it was reported independently by two persons. Perhaps they renamed PKUNZIP.EXE to UNZIP.EXE, so that the parameter -s, used for UNZIP.EXE, lead to a password prompt with PKUNZIP.EXE. I hope this is fixed now though untested. - With LHA and LHARK now the parameter /a is used, so that also hidden and system files are correctly decompressed. 1.29b 09-21-97 - Some small fixes when unpacking with UNGTZ. 1.29c 09-22-97 - Fix: LHARK does not understand /a etc., only -a. 1.30 09-24-97 - Calling sequence for JAR now JAR16.EXE > JAR32.EXE > JAR.EXE. - Format CAR is beeing identified (only from extension .CAR). - Better detection of the formats Codec, Limit and ZIP-Archiv. 1.30a 09-27-97 - Better detection of WinRAR (incl. 2.02). - Default unpacker for LZH files (except -lhd-) is LHA.EXE again instead of LHARK.EXE (because LHARK.EXE cannot decompress LZS files). 1.30b 09-29-97 - Fixed GZip dekompression. - Adjust JAR parameters for version 1.02. - LHARK.EXE (-B) is again default unpacker for LZH, because LHA.EXE has problems decompressing absolute pathnames into a specific target directory. For method LZS (LARC) a new type (107) has been defined. LZS files are always unpacked with LHA.EXE. 1.30c 09-30-97 - With the parameter /M it is now possible to unpack the mail archives into an alternative directory. 1.30d 10-01-97 - If a target directory does not exist and cannot be created, UU now quits with an errorlevel 254. 10-02-97 - Parameters /V and /T did not work with RAR archives, if UNRAR.EXE instead of RAR.EXE was configured as unpacker. 1.31 10-11-97 - Also 32 bit WinZip sfxes are recognized (as ZIP). 10-13-97 - Another Windows install sfx format (ZIP) added. 1.31a 10-14-97 - Standard unpacker for HA is now LGHA.EXE by Lyapko Yuri Georgievich. - Replaced references to X1.EXE by X1DOS.EXE. - Simplified file access mode. 10-15-97 - Sometimes LHark archives were identified as AIN. 1.31b 10-29-97 - Better Novell Netware compatibility. 1.32 11-01-97 - Format BOA is being identified and unpacked. - Format Z (InstallShield) is being recognized and unpacked using ICOMP.EXE. 1.32a 11-08-97 - Formats ARG and Gather (GTH) are identified and unpacked. - RKive 1.9 is identified. 1.33 11-09-97 - When using the parameter /M (decompress mail archives) now only those files are unpacked, whose extension begin with 'SU', 'MO', 'TU', 'WE', 'TH', 'FR' or 'SA' and end with a number from '0'...'Z'. - Bugfix with /M: if a target path was given in addition to the mail path, only the first file was unpacked into this path, all others into the mail path (as if no alternative target path was given). 1.33a 11-27-97 - Formats Pack Magic, Big Tree Software Archiver, ELI 5750 and QFC are recognized (QFC also unpacked). 1.33b 12-01-97 - On an unpacker error (broken archive or the like) UU now returns the corresponding errorlevel of the unpacker.
